I am currently studying Newton-Raphson Method. I feel that I understand the concept of it. Somehow, I am facing some question in my head about how to actually apply it.
The questions that I have are below - How should I decide the first initial value? - How should I find all the roots on x-axis?, how should I set the ranges to find them separately?
Please, let me here your expertise. I am sorry if I have tagged my question in the wrong places. Thank you.
